  • Mark your chosen location with rope and create the shape you want for your pond.

  • Dig out a deeper second tier of your pond with approximate dimensions of 2 x 4-feet to a depth of approximately 6 inches.
  • This second tier will create a deeper middle portion for fish and create a shelf for plants and accessories around the edges.

INSTALL THE POND LINER AND UNDERLAYMENT

  • Clear any debris from the pond hole that could potentially puncture the liner. 
  • Press the liner into all gaps to ensure a proper fit.
  • Leave at least a 10-inch overhang.
  • Remove the liner and create the underlayment to provide additional protection for the liner. Two layers of underlayment are recommended.
  • Once the underlayment is complete, reinstall the liner and construct a ledge using decorative rocks to sit inside and hide the liner overhang. The ledge should be a few inches deep.

FILL THE POND
